Fig. 5: Experimental setup to observe the topological resonance.

From: Topological resonances in a Möbius ring resonator

Fig. 5

The port2 and port3 are connected with a tunable flange to form a polarization-maintaining (PM) ring resonator, the transmission signal is collected with a detector and the transmission spectrum is observed on the oscilloscope (OSC).
